2019-08-05
13:19
Fix a problem with renaming a table when a view or trigger within the schema uses a FILTER with an aggregate function that is not currently registered with the database. check-in: 2ac0e42f8a user: dan tags: trunk
12:55
Prevent an fts5 table from being its own content table, or part of a view that is the content table. check-in: b6d52c9364 user: dan tags: trunk
2019-08-03
19:06
Strengthen an assert() in the WHERE clause code generator for the min/max optimization. check-in: 1bd4b97d64 user: drh tags: trunk
16:37
Fix a problem with queries of the form "SELECT min(<expr>) ... WHERE <expr>=?" where there is an index on <expr>. Fix for [71e183ca]. check-in: d465c3eef4 user: dan tags: trunk
16:17
In the ".wheretrace 0x100" debugging mode, show the structure of the main parameters to sqlite3WhereBegin() calls. check-in: fd598e475d user: drh tags: trunk
01:40
Add the SQLITE_TESTCTRL_PRNG_SEED which can control the PRNG seed either directly or through the schema cookie of a supplied database connection. check-in: 2660e9292a user: drh tags: trunk
01:39
Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not NULL is a pointer to a database connection which seeds the connection from its schema cookie. In this way, fuzzers can control the PRNG seed. Closed-Leaf check-in: 49aa344806 user: drh tags: prng-seed-test-control
2019-08-02
21:03

If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Fix for ticket [41866dc37]. check-in: faaaae4940 user: dan tags: trunk
18:43
If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Possible fix for ticket [41866dc37]. Closed-Leaf check-in: a7277ed062 user: dan tags: tkt-41866dc37
2019-08-01
22:48
The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer. And statements that are running when sqlite3_set_authorizer() is invoked should be allowed to continue running to completion. check-in: 961e2f08c3 user: drh tags: trunk
15:18

21:08
Update "releasetest_data.tcl" so that it is a standalone script that generates sh or batch scripts to run each tcl test run at release time. Update wapptest.tcl to use it. check-in: 559c2dd672 user: dan tags: trunk
15:16
New test cases in test/fuzzdata8.db. check-in: 6e92d71c24 user: drh tags: trunk

21:00
Fix the build for when -DSQLITE_SMALL_STACK is used. check-in: b9eda2249a user: drh tags: trunk
14:22
Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query. This undoes check-in [a871d69c6de65038] and substitutes a new fix. check-in: 89bf0399e8 user: drh tags: trunk
01:17
Disable the skip-scan optimization for DISTINCT queries. Fix for ticket [ced41c7c7d6b4d36] check-in: a871d69c6d user: drh tags: trunk

14:42
When using an index for both DISTINCT and ORDER BY, do not confuse the number of columns required for distinctness with the number required to get the correct sort order. Fix for [6749cb3c]. Closed-Leaf check-in: b47169319a user: dan tags: tkt-6749cb3c
06:06
Fix the OP_Affinity operator so that when applying REAL affinity, it only sets MEM_IntReal if the integer value will fit in 6 bytes or less. Fix for ticket [ba2f4585cf495231] check-in: 2b221bb15f user: drh tags: trunk
05:23
Fix a minor typo in a comment. check-in: cea8a892f7 user: drh tags: trunk

20:10
Improve the ".recover" command so that it handles intkey pages linked into non-intkey b-trees, and vice-versa, better. check-in: 9c458acba5 user: dan tags: trunk
19:20
Improve the ".recover" command's handling of corrupt database schemas. check-in: becaaa4d29 user: dan tags: trunk
08:15
Improve the ".recover" command in the shell tool so that it is not confused by auto-vacuum databases. And so that it can recover tables for which one or more of the column names are SQL keywords. check-in: 87d76047d6 user: dan tags: trunk
2019-07-23
